Master JavaScript Interview Questions Series

Learning JavaScript is a pivotal step for any aspiring web inventor, and interviews can be a daunting task. In this series of papers, we’ll explore essential JavaScript motifs in our website, Okpediaa that will help you attack indeed the interview questions with ease.

We will dive into each content with clear explanations, terse law particles, and real– world exemplifications, making it easy for you to learn and apply these chops in your own systems.
By the end of this series, you will be well- equipped to handle common JavaScript interview questions and take your coding chops to the coming position.

So, let’s get started and explore the world of JavaScript together!

Remove indistinguishable rudiments from an Array

To remove indistinguishable rudiments from an array using JavaScript, you can use the following approach:

Copied!const array( 1, 4, 5," Banana", 6, 1, 4, 4, 9, 3," Banana");

const uniqueElements = array.filter(( element, indicator) returnarray.indexOf( element)});

indicator (unique rudiments);

// Affair( 1, 4, 5," Banana", 6, 9, 31)
const array( 1, 4, 5," Banana", 6, 1, 4, 4, 9, 3," Banana");

const uniqueElements = array.filter(( element, indicator) returnarray.indexOf( element)});

indicator (unique rudiments);

// Affair( 1, 4, 5," Banana", 6, 9, 31)

Write a Function to induce a Fibonacci series of a given length.

Copied!function fibonacci( length){

// Initializing the array with the first two figures of the series

const fibArray = ( 0, 1);

// Generating the rest of the series

for( let i = 2; i< length; i){

(fibArray( i- 1) fibArray( i- 2));

return fibArray;

const series fibonacci(7);

( series);
// Affair( 0, 1, 1, 2, 3, 5, 8)
function fibonacci( length){

// Initializing the array with the first two figures of the series

const fibArray = ( 0, 1);

// Generating the rest of the series

for( let i = 2; i< length; i){

(fibArray( i- 1) fibArray( i- 2));

return fibArray;

const series fibonacci(7);

( series);
// Affair( 0, 1, 1, 2, 3, 5, 8)

Rear String using inbuilt styles and without styles

Reversing string with styles

Copied!let string = " javascript";

let reversedString = string.split("). reverse(). join('');

(reversedString);

// Affair tpircsavaj
let string = " javascript";

let reversedString = string.split("). reverse(). join('');

(reversedString);

// Affair tpircsavaj

Converting string to array of characters

Reversing string without styles

Repeating over the string from the last character to the first character.

Copied!let string = " javascript";

Let reversedString = '';

for( let indicator = string. length 1; indicator> = 8; indicator-)

reversedString = string( indicator);

reversedString);

//Affair spirosavaj
let string = " javascript";

Let reversedString = '';

for( let indicator = string. length 1; indicator> = 8; indicator-)

reversedString = string( indicator);

reversedString);

//Affair spirosavaj

Exchange the values of two variables without the need for a temporary third variable.

Copied!let x = 5;

let y = 10;

x, y) = ( y, x);

( x);// 10

();// 5
let x = 5;

let y = 10;

x, y) = ( y, x);

( x);// 10

();// 5
